Their first payment was $1,160, and their first grocery bill was $130. Caroline claims the she owes $322.50 toward theses two costs. Is her claim correct?

Respuesta :

Answer:

She is correct

Step-by-step explanation:

The total amount the three roommates must pay is $1,160+$130= $1,290

Allison must pay:

$1,290*0.35= $451.5

Betsy must pay:

$1,290*0.4= $516

Both Allison and Betsy payments sum: $967.5

Caroline must pay: $1,290-$967.5= $322.5

She is correct because she agreed to pay the remaining balance, which in this case is $322.5
